[iOS] Free - Tonality: Piano/Guitar Chords - Apple Store

This seems to be an useful app for the musicians among you. Apparently the IAPs are for tips only, so not necessary.

From the website:

The ultimate chord, scale, and music theory reference tool for musicians of all skill levels. Tonality allows you to view and hear a large database of piano/guitar chords and scales. You can run Tonality as an AUv3 MIDI receiver and view piano chords that match MIDI input you route to it, or as a MIDI source and send chords to other apps.

NOTE: Tonality will always be a one-time purchase with free upgrades. All IAPs are for tips only.
